VAPOR-CONDENSER.

SPECIFICATION forming part of Letters Patent No. 587,842, dated August10, 1897.

Application filed October 9, 1395.

To all whom it may concern:

Be it known that I, SAMUEL G. MERRICK, residing at Philadelphia, in thecounty of Philadelphia and State of Pennsylvania, have invented certainnew and useful Improve ments in Vapor-Condensers, of which the followingis a specification, reference being had therein to the accompanyingdrawings.

This invention relates to machines or apparatus for condensing fumes,destroying noxious vapors, securing by-products of combustion,vaporization, or distillation, and other like purposes.

The object of the invention is to improve mechanisms heretofore devisedfor such purposes.

Figure l is a longitudinal section showing the essential parts of amechanism devised for this purpose; Fig. 2, a cross-section on line soa: of Fig. 1; Fig. 3, a cross-section on line y y of Fig. l.

The drawings are intended to be merely diagrammatic, as illustrating thegeneral features of my device in one form only.

Many modifications are within the spirit of the invention and theclaims.

The reference-letter A indicates the box or casing, which should bewater-tight at the lower part and preferably air-tight at the upperportion, except the inlet for smoke or gases, which may be of suitableform and location, as at A The casin g should be pitched, painted, linedwith glass or porcelain, or otherwise made durable against the attacksof gases or chemicals used in disinfecting or condensing. This box orcasing is divided into two parts or chambers K and L by the partition B.

The shaft 0 extends from end to end of the casing, passing through andsupported -in suitable stuffing-boxes D D at the ends.

The shaft is driven from pulley E or in any other suitable manner.Around shaft 0 are coiled pipes F F, which are rigid with the shaft, andare supported to move with said shaft by spiders or similar supports Gon the shaft.

A diaphragm or disk H may support the tubes F in line with the partitionB, and the outside of the tubes may have a collar I'attached, thusforming a bearing for the tubes Serial No. 565,174. (No model.)

at the partition B and cutting off the passage through thecylinderformed bythe coils of tube, so that there is but littlecirculation of liquid round the coils in backward direction.

The receiving-chamber K and the condensing-chamber L are preferablypartly filled with water or other liquid, which may be a chemicalreagent of the gases acted on.

The normal height of the liquid in the chambers is such as to cover thecoils in the chambers. The flaring months F F of the coiled pipes F Fwill then take in air or gas as the shaft 0 and its attached coilsrotate in proper direction, when the flaring mouths of said pipes areabove the liquid-surface, and, carrying the gases under theliquid-surface, will convey it along the coils, compressing andcondensing the gases therein, and finally 7o delivering the residuum incompartment L. Much of the gases so treated will be absorbed by thepressure and chemical action of the liquid on the gases in the pipes.The residue and some of the liquid will pass out of the ends F of thepipes during the rotation.

It sometimes becomes desirable to change the level of the liquid in thechambers or compartments K and L. Thus if the liquid in the compartmentL has its surface above that in compartment K there will be a greaterresistance and the gas will go forward under a greater pressure. If thereverse be the case, then there will be a suction through the pipes,other passages being approximately closed between said chambers.

Let N N represent the cylinders of a pump, which pump may be actuated byeccentricrod '0, connecting to an eccentric P on the shaft 0. This pump,of any suitable kind, communicates with the interior of the chambers Kand L by means of pipes S and suitable valves or cocks T. The rotationof shaft 0 then by means of the pn mps connected thereto forces theliquid from chamber K into chamber L, or by reversing the pump the watermay be drawn in reverse direction.

U U indicate regulating pipes or passages through the partition B, andby suitable cocks or valves in said passages, preferablycontrollable-from outside the casing, the comparative height or pressureof liquid or gases in either compartment may be maintained, and by thepump N a rapid circulation may be had.

To still further vary the pressure in the diiterent chambers, and toassist, if necessary or desirable, in drawing in the fumes or gases intochamber K, a fan or blower W may be connected to chamber K. As shown,this fan is inside the chamber and is driven by suitable driving meansfrom shaft C. It will readily be understood that the location may bejust outside the chamber and the power maybe otherwise applied. This fanor blower may be used to draw the gases into'the chamber K throughsuitable openings in the casing and to feed them directly to the coilsof the pipe, thus tending to increase the pressure in the chamber K andthereby raise the height of the liquid in the chamber L.

y indicates a passage between the chambers, above the water-line, bywhich the gases or fumes once passed through the coils may be allowed toreturn for a second treatment. Preferably this passage should beprovided with a check-valve. A pipe or passage Z may be provided toconvey away the gas not absorbed or condensed. A pipe or cock U may beused to draw oft liquid.

The mechanism I have described is a development of and improvement onthe mechanism patented to Kirk and Ayers, No. 153,173, of July 21, 1874,and, as will be readily understood by a person skilled in the art, willadmit of great modifications without essentially departing from, thegeneral idea of the improvement, which is to control the relative heightof the liquid in the receiving and condensing chambers of the apparatusand to control the pressures and circulation of both the gases andliquids more perfectly than has been done heretofore.

What I claim is- 1. In a condenser for gases and the like, thereceiving-chamber, the condensing-chamber, and a coiled pipe having itsinlet in the receiving-chamber and its outlet in the condensing-chamber,means for rotating said coil, a liquid-supply inthe chambers, and means"driving said pump, all combined substantially as described.

3. In a vapor-condenser of the character described, the casing havingreceiving and condensing chambers separated by a partition, the rotatingcoiled pipe having one end in each chamber and passing with an ap--proximately closed joint through said partition, and passages throughthe partition controlled by suitable valves, all combined substantiallyas described. 7

4. The condenser having receiving and condensing chambers and therotating coiled tube having one end in each chamber, and passing throughthe dividing-partition with an approximately closed joint, thevalve-controlled passage through said partition, and the pumpcommunicating with the two chambers, all combined substantially asdescribed.

5. In a vapor-condenser, the combination of the receiving and condensingchambers having a liquid therein, the rotating coiled pipe having oneend in each chamber, and the fan in the receiving-chamber operativelyconnected to the rotating coil, all combined substantially as described.

6. In a vapor-condenser, the combination of the receiving and condensingchambers, the rotating coiled pipe communicating with each, theliquid-supply in said chambers, and a'ci'rculating-pump in one chamberand driven by the coil-drivin g mechanism, all combined substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.
